The nitty-gritty.

I thought I'd mention a few more design considerations of the server!

The less holes there are, the less chance for noise to escape! As mentioned before the buttons are made from cast acryllic but I forgot to mention they are transparent so that we can use them as status indicators, so the production version will no loger have the holes next to the buttons for indicators... less holes less noise to escape from! The production version will also have a velvet curtain over the CD slot as the last hint of noise was heard through the CD slot in the prototype, so we have now addressed that problem too... every little helps!

Notice the side panels are recessed in the server. Apart from showing off the thickness hence sturdiness of the case, these side panels are made from 2mm thick aluminium and shaped to fit the hole. As the case is made from an extruded tube, the holes on these tubes will never be all exactly the same. Hence the side panel will always need to be slightly smaller than the tune's hole, hence the side panels were designed to "expand" when you tighten the side screws in order to seal the tube sufficiently.

Why recess them? Well it was an insurance policy during the design phase. The idea was to allow extra damping material to be added on both side of the side plate should we need to take the noise down another level! Fortunately the pre-production unit proved that was no longer necessary as the noise supression was already so effective, so now it simply leaves scope for the customer to specify a different custom side finish... Penaudio ply veneer anyone? :o)
